Military veterans huddle together to hold an American flag against strong winds during a march Monday to a closed bridge outside the Oceti Sakowin camp where people have gathered to protest the Dakota Access oil pipeline in Cannon Ball, North Dakota.
Industry leaders are urging President-elect Donald Trump to make approval of the disputed Dakota Access oil pipeline a “top priority” when he takes office next month, while opponents who have protested the project for months are vowing to stay put on their sprawling North Dakota encampment despite harsh winter weather and a tribal leaders’ call to leave.
The moves come after the Army declined to issue a permit for the $3.8 billion pipeline to cross under a Missouri River reservoir in southern North Dakota near the Standing Rock Sioux Reservation. While the Army’s decision doesn’t end the debate over the pipeline, industry analysts and the chairman of the Native American tribe that’s led the protests said Monday they don’t expect any developments for months.

The motorcade carrying the ashes of late Cuban leader Fidel Castro makes its final journey toward the Santa Ifigenia cemetery in Santiago, Cuba, on Sunday. Thousands of people lined the short route from the Plaza of the Revolution to the cemetery.
The wooden box containing Castro’s ashes was placed by his brother and successor on Sunday into the side of a granite boulder that has become Cuba’s only official monument to the charismatic bearded rebel who seized control of a U.S.-allied Caribbean island and transformed it into a western outpost of Soviet-style communism that he ruled with absolute power for nearly a half century.
The private, early-morning ceremony was attended by members of Fidel Castro’s family, the ruling Politburo of the single-party system he founded, and Latin American leaders who installed closely allied leftist governments in Venezuela, Bolivia, Nicaragua and Brazil.

Maine Gov. Paul LePage has twice been elected in three-way races with less than a majority of the vote. But now, Maine has changed how it will choose most officeholders, becoming the first state in the country to adopt ranked-choice voting, also known as instant-runoff voting, which allows voters to list candidates in order of preference so that if in the first round no one wins a majority, officials can recount the ballots immediately until someone does.
